KanaRx — Pure Kanamycin Sulfate
The deep, broad-spectrum antibiotic you reach for when an infection has moved past the early stage. KanaRx is 100% pure kanamycin sulfate — it penetrates into tissue far better than surface treatments and keeps working even when a fish has stopped eating, making it the strong choice for serious, resistant, or suspected internal infections.

When KanaRx makes sense
- A fish is going downhill or not responding to earlier treatment.
- You suspect a deeper or internal bacterial infection.
- Visible infections aren't improving with NitroCure or KoiCure.
- You need a treatment that works even when fish won't cooperate.
Where it fits: KanaRx is the step-up, not the first move — start with NitroCure or KoiCure, and escalate to KanaRx for serious or internal cases. Can also be mixed into medicated food. Follow label directions for dosing & schedule. Guidance only — not veterinary advice.
